Title: Manufacture of diazotizable azo-dyestuffs and intermediate products therefor
IPC: C09B35/18
Filed: 1925-09-28
Abstract: 252,957. Chemical Works, formerly Sandoz, and B÷niger, M. Sept. 28, 1925. Pyrazolones. - 2<1>-Methyl-3<1>-nitro-5<1>-sulpho-1- phenyl-3-methyl-5-pyrazolone, and the corresponding 3-carboxylic acid, are obtained by condensing 6-nitro-2-tolylhydrazine-4-sulphonic acid (obtained by reducing the diazo-compound of 6- nitro-2-toluidine-4-sulphonic acid with sulphurous acid) with ethylaceto-acetate or ethyloxalo-acetate. The corresponding amino-pyrazolones are obtained by reduction. Disazo ayes which can be diazotized on the fibre and developed with unsulphonated azo components, are obtained by coupling the intermediate product from one molecule of the tetrazo compound of a p-diamine and one molecule of an aryl-o-oxycarboxylic acid with one molecule of one of the above pyrazolones, the nitro group being subsequently reduced to the amino group if the nitro-pyrazolones are used, or the tetrazo compound may be first combined with one molecule of the pyrazolone, and then with one molecule of a component. According to examples (1) benzidine is diazotized and coupled with o-cresotinic acid and 2<1>-methyl-3<1>-amino-5<1>-sulpho-1- phenyl-3-methyl-5-pyrazadone ; (2) dianisidine is diazotized and coupled with salicylic acid and the corresponding pyrazolone-3-carboxylic acid; (3) tolidine is coupled with the above nitro-pyrazolone-3-carboxylic acid and 2-amino-8-oxynaphthalene-6-sulphonic acid, and the nitro group is reduced. The second coupling component may be. an amine, phenol, pyrazolone, naphthol, aminophenol ether, aminonaphthol ether, aryl-ooxycarboxylic acid, aminophenol sulphonic acid, naphthylamine sulphonic acid, aminonaphthol sulphonic acid, amino-phenyl-1 2-naphthimidazole- 5-oxy-7-sulphonic acid, or amino-benzoyl-2-amino- 5-naphthol-7-sulphonic acid. The products, which dye cotton directly in various shades from orange and red to dark brown, can be diazotized on the fibre and develoned with #-naphthol, mdiamines, or phenylmethylpyrazolone, producing similar shades which are very fast to washing. The direct dyeings can also be made fast to washing by after treatment with p-nitrodiazobenzene or formaldehyde. Trisazo dyes are obtained by coupling one molecule of a tetrazotized p-diamine with one molecule of one of the above pyrazolones and with one molecule of a monoazo dyestuff obtained by coupling a diazotized p-phenylene-diamine sulphonic acid with a m-diamine. In an example, benzidine is diazotized and coupled with one molecule of 2<1>-methyl-3<1>-amino-5<1>-sulpho-1- phenyl-5-pyrazolone-3-carboxylic acid and with one molecule of the monazo dye made from the diazo compound of p-phenylene-diamine sulphonic acid and m-toluylenediamine.

Horse and hair clippers .-An apparatus for shearing sheep, clipping horses, &c., of the type in which the top cutter-plate is actuated by an oscillating arm which is secured to a spindle, and in which a presser-plate is inserted between the arm and the top cutter-plate so that the pressure between the cutter-plates can be adjusted, is provided with two separate mannally-operable means for adjusting the pressure between the plates. Fig. 2 shows an arrangement in which the presser-plate H can be adjusted by screwing the cap D<1> into the frame A and then tightening the screw H<1>. The frame A is of aluminium, and the lower cutter-plate F is secured to a steel plate E which is secured to the frame. The spindle D is mounted in a hole formed in the plate E. The oscillatory movement of the actuating arm C is transmitted to the presser-plate H by the pin C<2> which is secured to the arm C. The driving shaft B may be rotated by hand or power, and when power is employed the motion is transmitted by means of a skew-gear to prevent undue vibration reaching the hand of the operator. In a modification, the presser-plate does not extend around the spindle D but is replaced by two plates K, K<1>, Fig. 8, which extend across the top cutter-plate G at the front of the actuating arm C. The upper of these plates is curved longitudinally and the lower transversely. The pressure on the top cutter-plate is finally adjusted in this case by tightening screws L which pass through the presser-plates and connect the upper cutter-plate G to a pair of parallel-motion links J which at their other ends are pivoted to the framework.
